Giants co-owner John Mara tried a Hail Mary pass yesterday to get out of jury duty — but his request was quickly sacked by the judge.

Mara was selected as an alternate juror for a major international drug trial in Manhattan federal court. The case is set to last three weeks.

But Mara — whose league is currently in the middle of a work stoppage — called a timeout and approached the bench to speak with Judge Jed Rakoff about getting cut.

“My only issue, your honor, is the third week in here because we’re approaching the NFL draft. It is a big, big period for us, and I need to be at [work] during that period,” Mara said. “That’s my only issue. If it was just two weeks, I would be OK.”

The draft begins on April 28.

Rakoff said the third week of the case would be shortened because of Easter and Passover.

Then Mara added that maybe he wouldn’t be available for any of the trial.

“My only other issue is we’re in a lockout situation . . . and I’m one of the lead negotiators for the owners’ side,” Mara said. “So if for some reason negotiations start again, that causes me an issue.”

Rakoff then held out the option for an audible, saying he’d consider pulling Mara if “a real emergency” happens.
